Green Affordable Housing: What is it? Why do it? Can We Afford it? Where are the leaders going? New Ecology, Inc. Terner Symposium
What does it mean to be green? • Energy and water conserving • Healthy, improved IAQ • Durable • Siting • Materials New Ecology, Inc. Terner Symposium
Green? Why Should I Care? • Global Warming • Operations Costs • Risk Mitigation New Ecology, Inc. Terner Symposium
Green? Why Should I Care? • Buildings Use 36% Total US Energy; • Make 30% of Greenhouse Gases New Ecology, Inc. Terner Symposium
Green? Why Should I Care? New Ecology, Inc. Terner Symposium
Green? Why Should I Care? • Costs less to operate!! • Use 30-50% less energy than code buildings to heat and cool • Use 20% less electricity New Ecology, Inc. Terner Symposium
Green? Why Should I Care? • Costs less to operate!! New Ecology, Inc. Terner Symposium

Green? Why Should I Care? Healthier • Asthma mitigated with better IAQ and IPM • Compare commercial -- cannot quantify productivity, employee retention, sick days usage New Ecology, Inc. Terner Symposium
Green? Why Should I Care? Choice of Materials & Construction Techniques makes projects more durable & cheaper to maintain New Ecology, Inc. Terner Symposium
Green? Why Should I Care? • Attention to Landscaping and Siting results in: • landscapes that are easier to maintain and provide more amenities to occupants • Infiltrate stormwater – often reducing costs New Ecology, Inc. Terner Symposium
Mitigating Risk Major Risk Factors Addressed by Green Strategies • Poor design and construction • Cost overruns • Higher Than Projected Operating Costs New Ecology, Inc. Terner Symposium
Mitigating Risk • Higher Than Projected Operating Costs • Energy Budgets: 25% of operating costs and climbing • w/ annual 10% increases: >30% in 5 years • 20% increases > 40% in 5 years • Similar for high rate sewer districts New Ecology, Inc. Terner Symposium
Mitigating Risk Major Risk Factors Addressed by Green Strategies • Poor design and construction • Cost overruns • Higher Than Projected Operating Costs • The Next Lead Paint-type issue? New Ecology, Inc. Terner Symposium
Analyzing Risk • The Next Lead Paint-type issue? • Asthma: increasing evidence that IAQ has a significant effect on attacks: Potential liability for not reducing triggers? • Mold • Pesticide exposure New Ecology, Inc. Terner Symposium
Can We Afford It? • Cost of Greening • (as % of total construction costs w/o PV) • Mean: 4.95% • Median: 3.83% • Range: -25% to 38.94% • (11 of 16 cases under 5%) $20.00 on line @ www.newecology.org New Ecology, Inc. Terner Symposium
